Founded by Army veteran Tom Morneault, our team brings discipline, integrity, and certified expertise to every mold remediation project. We safely test, remove, and prevent mold in homes and businesses across Waltham—delivering fast, reliable results you can trust.
Morneault Environmental, based in Chelmsford, MA, offers expert mold removal and remediation services for Waltham residents and surrounding communities. With its combination of older buildings, humid summers, and water-adjacent neighborhoods near the Charles River, Waltham is especially vulnerable to mold growth—especially in areas like Ward 6, Lakeview, and downtown properties. Mold can spread swiftly in basements, bathrooms, attics, or any damp, poorly ventilated space. Inhaling mold spores increases your risk of allergies, asthma, and long-term respiratory problems. That’s why it’s critical to hire a licensed professional who understands the environmental conditions unique to Waltham. Our team is trained to identify, remove, and prevent mold—keeping your home or business safe and your air clean.

Mold is a fungus that thrives in damp, dark environments—often developing in homes where there's poor ventilation, roof leaks, or flooded basements. In Waltham, aging infrastructure and proximity to waterways like the Charles River increase the chances of mold—especially during humid summers or after severe storms. Once mold finds moisture, it spreads easily through drywall, ceilings, and floorboards. Breathing mold spores can cause ongoing respiratory issues including sneezing, coughing, sinus infections, and asthma. It's particularly dangerous for kids, the elderly, and anyone with allergies or a compromised immune system. Even mild exposure can become serious if untreated. That’s why expert removal is so important—it’s not just about cleaning but about protecting your health and your home’s structural safety.

With many buildings in Waltham dating back 50 years or more, and weather patterns contributing to wet, humid environments, the risk of mold is significant. Our certified team is equipped to identify mold at its source, remove it safely, and restore indoor air quality to meet city codes and health standards. Whether you're managing a Victorian on Moody Street or a multi-unit building near Brandeis, we understand the local architecture and moisture issues that often lead to mold. We handle every project professionally—with minimal disruption, thorough cleanup, and advanced methods to prevent regrowth. When you work with us, you get high-quality service you can trust. Mold inhalation can have lasting health risks and sometimes fatal outcomes. If exposed long-term, spores can lead to chronic respiratory illness or irreversible lung damage. It's more than just a nuisance—it's a silent threat to health. Our thorough remediation ensures every contaminated area is safely treated and secured, so your loved ones or tenants are no longer at risk.
